A-199 Spring Reverb Module : Slightly bigger spring tanks would give deeper sound

The A-199 Spring Reverb is a nice addition to the system if you don't want DSP, I would say once paired with the BBD you'd have all you need in terms of effects. In my opinion the spring tank is a bit small, I agree it has to fit in the case, however, it is very sensitive to magnetic fields and to make it run silently I have to have it outside the case, so even if the spring tank was larger it would have been fine. Other than that it sounds good.

Edit: The noise it produced despite its placement far away from MF was due to poor quality RCA cables supplied with old units. I found this out after I got in touch with Dieter Doepfer, who, kindly sent me the better quality cables needed. Now everything runs smoothly and quiet!
